The crash was reported about 1:50 p.m. near Oregon 47 and Maple Street and the driver of the 1987 gray Toyota Supra may still be in the area, said Capt. Mike Herb, a Forest Grove police spokesman. The driver appears in his 40s with a straggly beard and the car has an Oregon license plates 768FWP.

The Jeep was carrying a man, woman and three children, Herb said. The collision caused the Jeep to overturn, according to Herb. The crash has temporarily closed a portion of Oregon 47.

The man was flown to OHSU Hospital with life-threatening injures after apparently being thrown from the Jeep, said Matt Johnston, a Forest Grove Fire & Rescue spokesman. The woman was also taken to OHSU Hospital as a precaution and the three children were not hurt.

Anyone with information on the gray Toyota or the driver is asked to call the Washington County non-emergency line at 503-629-0111.
